T-Mobile showed up a wee bit late to the 4G LTE party, having first launched its LTE network in barely more than half a dozen markets six months ago. Making up for lost time, the fourth largest wireless carrier in the U.S. announced that its 4G LTE network now reaches 180 million people in 154 metro areas across the country..

This is on top of T-Mobile's 4G HSPA+ network, which the company claims reaches 228 million people. While T-Mobile's 4G LTE expansion over the past six months is impressive, it has a long way to go before it catches up with most of the competition, save for Sprint. It's also worth noting that T-Mobile only added 38 new markets covering an additional 23 million people since its last 4G LTE progress update back in July.

In any event, Verizon is currently casting the biggest net with its 4G LTE service available to more than 298 people in 500 markets. That works out to over 95 percent of the U.S. population.

AT&T is next in line with 4G LTE being offered to more than 225 million people in nearly 400 markets across the nation. Out of the four major carriers, only Sprint has a smaller 4G LTE network than T-Mobile. As of the end of July, Sprint said its coverage extends to 151 markets.
